Abstract
The present invention relates to a high-energy secondary electron detector comprising a collector P supporting only three electrodes that are insulated from one another and that are biased relative to the collector:
- a first repulsion electrode A1 for repelling charges of a first predetermined sign that are to be repelled, this negatively-biased electrode being provided with at least one opening for passing electrons;a second repulsion electrode A2 for repelling charges of the opposite sign that are to be repelled, this positively-biased electrode also being provided with at least one opening for passing electrons; anda selection electrode A3, this electrode also being provided with at least one opening for passing electrons;the openings in said electrodes being in alignment along a conduction cylinder D.Furthermore, the selection electrode A3 is negatively biased.
